Re: [xsl] checking sequence inside processing-instruction

["Ganesh Babu N" <nbabuganesh@xxxxxxxxx>]

Hai all

I am having another question on this post. In another project I have
encountered a processing instruction as <?page 5?> in this how can i
get the value 5 in a test to check the sequence with other pages.

<?page 5?>
<?page 6?>
<?page 8?>

The style sheet should tell <?page 8?> is out of sequence.

Regards,
Ganesh
